Developing Key Sustainability Competencies Through Real-World Learning Experiences: Evaluating Community Environmental Services, Erin Lorene Anderson
Dissertations and Theses
This study focuses on sustainability in higher education and the competencies essential to address sustainability issues. Because sustainability issues are complex, "wicked", and dynamic, sustainability education programs need to reflect the interdisciplinary and collaborative nature of the field. Graduates who are competent in sustainability research and problem solving will have the knowledge, skills, and attitude necessary to analyze a sustainability problem systemically and comprehensively, then will construct and implement interventions to reach optimal sustainability solutions. To prepare graduates, sustainability education programs should facilitate the development of key sustainability competencies (Wiek, Withycombe, & Redman, 2011). Such programs provide an interdisciplinary approach …
Insomniac Of The Soil: A Collection Of Poetry And Essays, Sarah E. Golibart
Insomniac Of The Soil: A Collection Of Poetry And Essays, Sarah E. Golibart
Senior Honors Projects, 2010-2019
“Insomniac of the Soil” is a homage to a landscape that has deeply informed Sarah Golibart's life and her artistic voice – the tidewater flatlands of Virginia’s Chesapeake Bay peninsula where her family lives and where Golibart has worked on farms since high school. Both her poems and essays are earthy, imagistic, and grounded – quite literally – in the soil as well as in a sensibility of ecological ethics and sustainability. “Insomniac of the Soil” is also a love song to the fervent and fallow cycles of the soil.

Impacts Of Consumer Horticulture On Stormwater And Nutrient Management: Investigating Public Perception, Knowledge, And Practices In The Shenandoah River Watershed, Christopher P. Parker
Impacts Of Consumer Horticulture On Stormwater And Nutrient Management: Investigating Public Perception, Knowledge, And Practices In The Shenandoah River Watershed, Christopher P. Parker
Masters Theses, 2010-2019
The South Fork Shenandoah River is a tributary to the Chesapeake Bay that is a significant contributor to nitrogen and phosphorus that enter the Bay and leads to increased eutrophication. These nutrients also cause problems in the South Fork Shenandoah River. The United States Environmental Protection agency has implemented strict regulation to reduce nutrients entering the Bay by developing the Chesapeake Bay TMDL. While the TMDL has strict regulation on wastewater treatment, agriculture, and industry, there are still sources of nutrients entering the Bay through unregulated sources. Urban/suburban runoff is one of these sources, particularly runoff from home owner’s lawns. …
Adolescent Girls, Human Rights And The Expanding Climate Emergency, Holly G. Atkinson, Judith Bruce
Adolescent Girls, Human Rights And The Expanding Climate Emergency, Holly G. Atkinson, Judith Bruce
Publications and Research
Many adolescent girls—the poorest girls in the poorest communities—already live in an “emergency.” Humanitarian crises only amplify the call on their coping and caring capacities, while exacerbating their vulnerabilities. The frequency and intensity of emergencies, including natural disasters, conflicts, and infectious disease outbreaks such as Ebola, appear to be growing.1 These emergencies threaten entire communities and whole countries, often with global implications. Many become virtually permanent. The authors urge key actors responding to both the threats and opportunities that climate change poses to understand adolescent girls as exceptionally at risk on the one hand, and as exceptionally resilient and …
Boom Or Bust? Mapping Out The Known Unknowns Of Global Shale Gas Production Potential, Jérôme Hilaire, Nico Bauer, Robert J. Brecha
Boom Or Bust? Mapping Out The Known Unknowns Of Global Shale Gas Production Potential, Jérôme Hilaire, Nico Bauer, Robert J. Brecha
Physics Faculty Publications
To assess the global production costs of shale gas, we combine global top-down data with detailed bottom-up information. Studies solely based on top-down approaches do not adequately account for the heterogeneity of shale gas deposits and hence, are unlikely to appropriately capture the extraction costs of shale gas. We design and provide an expedient bottom-up method based on publicly available US data to compute the levelized costs of shale gas extraction. Our results indicate the existence of economically attractive areas but also reveal a dramatic cost increase as lower-quality reservoirs are exploited. At the global level, our best estimate suggests …

The energy industry (including the oil and gas industry) is facing unparalleled scrutiny and demands from stakeholders including investors, regulators (industry and environmental), communities, and other stakeholders. Sustainable development is one of the major concerns of the oil and gas industry. Companies are seeking to increase sustainability of their operations by considering environmental and Social concerns in addition to economic concerns. Oil and gas companies need to take decisions at different stages of the product life cycle (e.g. planning, design, exploration, production, and clean-up) which have direct or indirect impact on the organization's objectives. Addressing economic, technical, Social, and environmental …
Using The Triple Bottom Line To Select Sustainable Suppliers For A Major Oil And Gas Company, Pandarinath Adarsh Sunkari
Using The Triple Bottom Line To Select Sustainable Suppliers For A Major Oil And Gas Company, Pandarinath Adarsh Sunkari
Graduate Theses and Dissertations
Companies have primarily been focusing on the financial bottom line i.e., on increasing profits by increasing revenues and reducing costs. With high energy usage and environmental change posing threats to the environment and business operations, companies are now considering sustainability. Since some global suppliers have low cost labor, Social well-being and human development has also emerged as major goals of a company performing global operations. Focusing on these three goals is termed the "Triple Bottom Line" (TBL). We study and explore the TBL benefits that could be realized by an oil and gas company by focusing on sustainable suppliers. A …
Relationships, Knowledge, And Resilience: A Comparative Study Of Stakeholder Participation In Great Lakes Areas Of Concern, Kathleen Colin Williams
Relationships, Knowledge, And Resilience: A Comparative Study Of Stakeholder Participation In Great Lakes Areas Of Concern, Kathleen Colin Williams
Theses and Dissertations
This dissertation investigates the current practices of environmental governance in the Great Lakes region, where at one time the rivers that fed the Great Lakes were choked with debris and on fire. The Great Lakes Water Quality Agreement of 1978 and the 1987 updates inspired collective action to remediate and restore the rivers and nearshore zones of the lakes through the implementation of an ecosystem approach, which included a public participation dimension. While funding and momentum has fluctuated, the constructs – Areas of Concern (AOC), Remedial Action Plans (RAP), and Public Advisory Councils (PAC) persist. In 2010, the Great Lakes …
Sustainable Decolorization Of Reactive And Acid Dye Wastewater Using Photo-Fenton Oxidation Both With And Without Biodegradation: Laboratory And Field Studies, Marissa R. Jablonski
Sustainable Decolorization Of Reactive And Acid Dye Wastewater Using Photo-Fenton Oxidation Both With And Without Biodegradation: Laboratory And Field Studies, Marissa R. Jablonski
Theses and Dissertations
Photo-Fenton oxidation is an advanced oxidation process (AOP) used to degrade low-concentration textile dye wastewater using expensive chemicals. The technique has shown promise in laboratory-scale projects, but has not been scaled up sustainably to function for industry. Aerobic biodegradation is a common biological treatment method used in large-scale textile industrial applications that generates large amounts of hazardous biological waste. This waste is often left open to the elements and subsequently leaches into natural waterways or onto land. This is the first study of its kind to combine the two to treat cottage-scale industry-grade textile wastewater with a dye concentration of …
Characterizing Groundwater Ch4 And 222rn In Relation To Hydraulic Fracturing And Other Environmental Processes In Letcher County, Ky, St. Thomas Majeau Ledoux
Characterizing Groundwater Ch4 And 222rn In Relation To Hydraulic Fracturing And Other Environmental Processes In Letcher County, Ky, St. Thomas Majeau Ledoux
Masters Theses
Hydraulic fracturing of shale deposits has greatly increased the productivity of the natural gas industry by allowing it to exploit previously inaccessible reservoirs. However, previous research has demonstrated that this practice can contaminate shallow aquifers with CH4 [methane] from deeper formations. This study compares concentrations and isotope compositions of CH4 sampled from domestic groundwater wells in Letcher County, Kentucky in order to characterize its occurrence and origins in relation to neighboring hydraulically fractured natural gas wells. Additionally, this study tests the reliability of 222Rn [radon] as an alternative tracer to CH4 in identifying processes of gas …
The Effects Of Recreational Rock Climbing On Vascular And Nonvascular Plant Communities In Southeastern Tennessee, Caitlin A. Ruby
The Effects Of Recreational Rock Climbing On Vascular And Nonvascular Plant Communities In Southeastern Tennessee, Caitlin A. Ruby
Honors Theses
Popularity for non-consumptive outdoor recreations has rapidly increased over the past decades. With many national and state park regulations failing to regulate rock climbing, scholars are concerned for the amount of ecological disturbance that may occur if left unmonitored. Visual assessments to disturbance disparities between remote climbing locales and contradictory scientific literature confirmed the need for further research on the effects of rock climbing on cliff ecology. Two climbing centers were focused in Southeastern Tennessee: Foster Falls in Sequatchie County and Leda in Hamilton County. Convenience sampling was used to collect 24 transects from intermediately graded routes and 24 transects …
Decision Environments To Encourage More Sustainable Infrastructure Outcomes, Earl Shealy
Decision Environments To Encourage More Sustainable Infrastructure Outcomes, Earl Shealy
All Dissertations
Physical infrastructure (i.e. roads, pipelines, airports, dams, landfills, and water treatment systems) contributes directly to sustainability outcomes such as energy and water use and climate changing emissions. The infrastructure built today will likely impact future generations for many years. Planning, design and development decisions about infrastructure are critical to the future performance of these systems. Such decisions about infrastructure are complex with multiple variables, alternative options, and design stages. To manage decisions that exceed cognitive capacity to consider all options, decision makers often create mental shortcuts (heuristics), and accompanied errors (biases). The potential cognitive biases when dealing with complex decisions …
Robustness Of Spatial Micronetworks, Thomas C. Mcandrew, Christopher M. Danforth, James P. Bagrow
Robustness Of Spatial Micronetworks, Thomas C. Mcandrew, Christopher M. Danforth, James P. Bagrow
College of Engineering and Mathematical Sciences Faculty Publications
Power lines, roadways, pipelines, and other physical infrastructure are critical to modern society. These structures may be viewed as spatial networks where geographic distances play a role in the functionality and construction cost of links. Traditionally, studies of network robustness have primarily considered the connectedness of large, random networks. Yet for spatial infrastructure, physical distances must also play a role in network robustness. Understanding the robustness of small spatial networks is particularly important with the increasing interest in microgrids, i.e., small-area distributed power grids that are well suited to using renewable energy resources. We study the random failures of links …
The Gold Coast Transformed : From Wilderness To Urban Ecosystem, Tor Hundloe, Bridgette Mcdougall, Craig Page
The Gold Coast Transformed : From Wilderness To Urban Ecosystem, Tor Hundloe, Bridgette Mcdougall, Craig Page
Tor Hundloe
Extract: This is the story of a unique city, Australia’s premier tourist city, a city cut out of coastal vegetation, including paperbark swamps, mangroves and rainforests of worldwide significance. The city has a relatively short history as until half a century ago (two human generations) it was but several relatively small villages, each with its own natural and social features. Two generations is a very short time for a city to grow to be the sixth-largest in population in Australia and to have global recognition as the country’s beach playground. The Gold Coast ranks with Honolulu in Hawaii, with Palm …
Local Response To Climate Change: A Case Study Approach, Nora Gimpel
Local Response To Climate Change: A Case Study Approach, Nora Gimpel
Honors Theses
The scientific consensus on the causes and consequences of climate change is clear and experts continue to strongly recommend immediate mitigation and adaptation responses (IPCC, 2014). Responses to climate change are occurring at the international, national, and subnational level, but adaptation to climate change is also highly local. Local communities across the world are organizing groups and institutions to determine their best responses for local mitigation and adaptation actions. This study analyzed the formal local community organization, the Kalamazoo Climate Change Coalition (KCCC), and its structured activities in order to evaluate how Kalamazoo has responded to climate change. Methodology for …

Elisa E. Addlesperger
Elisa Addlesperger’s map, created as part of a final project for GEO 243 Remote Sensing, shows the impact of development on availability of farmland in four collar counties in northeastern Illinois: Kane, Kendall, Will and McHenry. Landsat 5 multi-band spectral images from 1987 and 2007 were processed to create classes showing development density in each respective year. Open or agricultural land is indicated with a bright green. Based on this visual analysis, substantial amounts of arable land have been lost to development in Chicago’s collar counties. According to the state Department of Agriculture, Illinois has lost over 3.6 million acres …
Peripheral No More: Repositioning Narratives For Empowerment And Change In Sustainability Education, Rell G. Ohlson
Peripheral No More: Repositioning Narratives For Empowerment And Change In Sustainability Education, Rell G. Ohlson
Leadership for Sustainability Education Comprehensive Papers
The field of sustainability education challenges dominant modes of thought, with a particular emphasis on the need for diversity and "multiple perspectives" in order to confront complex issues (Capra, 2005; Sterling, 2001; Wheatley, 2006). If this is the case, why are certain perspectives still missing and what narratives have been given prominence? This comprehensive paper examines the problems of a dominant narrative in sustainability education. In order for sustainability education to be truly transformative and empowering for students, leaders, and their communities, the narrative of sustainability must be repositioned from a dominant, white, middle-class context to one that affirms, values …

Understanding Social Resilience In The Maine Lobster Industry, Teresa R. Johnson, Anna M. Henry
Publications
The Maine lobster Homarus americanus fishery is considered one of the most successful fisheries in the world due in part to its unique comanagement system, the conservation ethic of the harvesters, and the ability of the industry to respond to crises and solve collective-action problems. However, recent threats raise the question whether the industry will be able to respond to future threats as successfully as it has to ones in the past or whether it is now less resilient and can no longer adequately respond to threats. Through ethnographic research and oral histories with fishermen, we examined the current level …

Spatial Analysis Of Passenger Vehicle Use And Ownership And Its Impact On The Sustainability Of Highway Infrastructure Funding, Matthew Volovski
Spatial Analysis Of Passenger Vehicle Use And Ownership And Its Impact On The Sustainability Of Highway Infrastructure Funding, Matthew Volovski
Open Access Dissertations
Across the United States, the sustainability of highway funding is at risk due to increasing need and uncertainty in the factors that drive revenue. Past studies on highway funding sustainability have identified that the root cause of changing highway revenue are the shifts in social demographics and economic characteristics. Unfortunately, from the revenue perspective (the focus of this dissertation), the ability of previous research to account for these factors has been rather limited in two ways; first, the inability to accurately assess current regional vehicle use (a typical prerequisite for statistical modeling of highway revenues) due to difficulties associated with …
